Extraction of Long-Range Distances between Spin-Labeled H3-H4 Dimers Agrees with a Tetrameric Conformation When Bound to Nap1

(A) Positions of spin labels on H4 R45 and H3 Q125 (green spheres) are shown on the structure of the tetramer taken from the nucleosome (PDB code 1KX5, images created with Pymol, http://www.pymol.org/).

(B) The background corrected dipolar evolution and the distance distribution for each labeling site in complex with Nap1 and Asf1 is shown (red trace). For comparison the tetramer value extracted from the tetramer alone is shown alongside (black trace).
